Function and Working Principle
The F3XD08-6F continuously monitors DC input signals from field devices and transmits their ON/OFF status to the FA-M3 CPU.
Each input channel is electrically isolated by photocouplers to improve noise immunity and system reliability. The CPU reads the input status during each PLC scan cycle and executes the programmed control logic accordingly. Configurable sampling times and interrupt functions enable rapid detection of critical events.
Operating Sequence
- Receive digital signals from field devices.
- Detect ON/OFF status changes.
- Convert electrical signals into digital data.
- Transfer input status to the PLC CPU.
- Execute the control program.
- Repeat the scan cycle continuously.
